I installed the Acroread package and it installed ok, but when I click on the sound file icon I now get a pop up box from Acrobat telling me I need to install a player. When I click the"ok" button to do so, I get a web page telling me

We're sorry, but the third-party media player required to play the selected media file in your Adobe PDF document isn't available for your system. No media player will be downloaded at this time.

.

It then lists a bunch of media player download sites (Flash, Quicktime, Realplayer, WMP).

This is exactly what happened when I tried this in MINT. In that case, I went a step further and installed Realplayer, but that made no difference (Acrobat Reader has a 'preferred media player' setting which is set to Realplayer by default and can't be changed !).
